grinding noise when releasing the gas pedal

SOLVED:
Finally solved the grinding noise issue:
- The delta between the diff side propshaft operating angle and axle operating angle was approx 2.5 degrees.
One of the rules regarding propshaft angle is : Operating Angle 1 vs Operating Angle 2: within 1 degree
I solved this by adding a wedge between the axle and the springs. New Operating Angle 1 vs Operating Angle 2 is 0.5 degrees.
No noise any more
Did not expect a few (2) degrees would make such a difference

How did you measure the angles as I have castor wedge in front axle due to prop appearing to short after fitting parabolics years ago would like to take them out but need to accurately check flange angles.
